hymenium somewhat waxy, even or rugose. The genus is 

 related to Cantharellus ..... Cratereilus 



Fructification coriaceous, pileate or resupinate, with no cuticle and 

 no intermediate layer of hyphae running longitudinally, sections 

 homogeneous in structure throughout ; spores usually echinulate 

 and colored ; basidia not cruciate . . . 'Ihelephora 



Fructification coriaceous or woody, pileate, effuso-reflexed or rarely 

 resupinate, containing an intermediate layer of hyphae running 

 longitudinally ; hymenium may or may not contain rough- 

 walled cystidia but no setae ; basidia not cruciate Stereum 



Like Stereum except that the hymenium is velutinous with brown 

 setae ....... Hymenochaete 



Fructification resupinate, without the intermediate layer of Stereum ; 

 hymenium somewhat waxy when fresh, often cracked on drying ; 

 basidia not cruciately divided, no cystidia ; spores hyaline 



Corticium 



Like Corticium except that the hymenium contains hyaline or sub- 

 hyaline, rough-walled processes or cystidia . . Peniophora 



Fructification effused, incrusting, waxy-gelatinous ; basidia cru- 

 ciately divided. Distinguished by the basidia from Thele- 

 phora, Corticium and Peniophora . . . Sebaciiia 



Fructification membranaceous, resupinate ; hymenium fleshy, pul- 

 verulent with the colored spores ... Coniophora 



Fructification floccose-coUapsing or like a resupinate mould ; 

 4-spored basidia are borne on long lax hyphae . Hypochnus 



Fructification waxy, parasitic on living plants, often deforming the 

 affected parts or organs ..... Exobasidium 



Fructification submembranaceous, cup-shaped, often pendulous ; 

 hymenium typically concave or discoid . . Cyphella 



Fam. 5. CLAVARIACEAE. 



Fructification fleshy, much branched ; branches flattened in a leaf- 

 like manner, with hymenium on both faces . Sparassis 



Fructification fleshy, branched or simple, not tomentose ; branches 

 typically terete, not splitting .... Clavaria

 branched ; basidia forked, 2-spored . . . Calocera
